fluid.wme.pwr.wroc.plCOMBUSTION AND FUELS HOW IMPORTANT IS NITROUS OXIDE N 2O? N 2Ois known is the as laughing gas. N 2Ohas contribution to the stratospheric ozone destruction In combustion processes N 2O is formed mainly in fluidized beds (N 2O content in flue gas up to 50 ppm). N 2Ohas also some contribution to NO emission, by chemical reactions with radicals O i ...

For stoichiometric methane combustion with air, the balanced reaction equation reads: CH 4 þ 2ðO 2 þ3:76N 2Þ!1CO 2 þ 2H 2Oþ 7:52N 2: (2.11) Note that on the reactant side there are 2·(1+3.76) or 9.52 mol of air and its molecular mass is 28.96 kg/kmol. In this text, the reactions are balanced using 1 mol of fuel.

The standard enthalpy of combustion for a substance is defined as the enthalpy change ∆H T o which accompanies a process in which the given substance undergoes reaction with oxygen gas to form specified combustion products [such as CO 2(g), H 2O(l), N 2(g), SO 2(g)], all reactants and products
STOICHIOMETRY OF COMBUSTION
fluid.wme.pwr.wroc.plThe reaction of its oxidation can by written by the equation of stoichiometry: CmHn + (m + n/4)O 2 →→→→mCO 2 + n/2H 2O 1 mol + (m + n/4)moles →→→→(m +n/2)moles This is an equation of stoichiometry of combustion.
